I got my driving license in Finland about 1 1/2 years ago and am thinking of moving away again. There is this slippery track training that you need to do after max 2 years, which I haven't booked yet. What if I don't live in Finland anymore? Would I have to come back to do it anyway, even though it's not required in other European countries? Or could I avoid the extra trip and 400€ for the training by switching my Finnish license to another country?
